GRAIN-ADJUSTING DEVICE FOR GRAIN-BINDING MACHINES.

SPECIFICATION forming part of Letters Patent No. 359,426, dated March15, 1887.

No model To all whom it may concern.-

Be it known that I, HENRY J. OAsE, of Auburn, in the county of Cayugaand State of New York, have invented certain ImprovementsinGrain-Adjusting Devices for Grain-Binding Machines, of which thefollowing is a specification.

Thisinvention has reference to what are commonly known in the art asbutting-aprons, or butt-adjusters, which consist of an endless apronhaving vertical faces mounted on a swinging or adjustable frame locatedordinarily across the, end of the bindingtable, with the operative facein aline oblique to the path of the grain, for the purpose of actingagainst the butts of the grain-and forcing the same endwise upon thetable, in order that it may be broughtinto the proper relation to thebinding devices.

The principal objects of my invention are to provide for the moreconvenient adjustment of the tension of the apron, to facilitate itsremoval and replacement, and-to cheapen the cost of construction.

In the accompanying drawings, Figure 1 represents a side elevation of myimproved adjusting mechanism, together with the bindingtable and otheradjacent parts, in so far as it is necessary to an understanding of myinvention. Fig. 2 represents a side elevation of the supporting-framewith the apron removed therefrom. Fig. 3 is a longitudinal verticalsection through the lower end of the frame. Fig. 4. is an end viewthereof. Fig. 5 is a side view of the roller by which the lower end ofthe apron is carried, the openings therein being indicated in dottedlines. Figs. 6 and 7 are side elevations of the two parts of theroller-supporting slide or bracket- Figs. 8 and 9 are end views of thesame. Fig. 10 is a side view of the bolt and nuts by means of which thesliding frame is adjusted and secured. Fig. 11 is an under face viewofthe top board of the frame, showing the openings therein.

Referring to the drawings, Arepresents the endless apron or canvas,sustained at its two ends by the uprightrollers B and O, mounted inaframe, D, which is arranged to swing horizontally about the axis of theupper roll 0, in order to change the obliquity of the face of thethereover off from the rolls.

belt with reference to the path of the grain.

E represents a metallic bracket, constructed in two parts, in which theupper and lower journals of the lower roll 0 are sustained, the upperend of the bracket being attached to the remaining portion by a bolt, 6,so that it may be readily removed when the belt or apron is to bedetached.

The foregoing parts, as regards their general construction and mode ofoperation, are similar to those now in use in the art.

Instead of constructing the swinging frame, the rollers, and the lowerroller-bearingin the ordinary manner, I adopt the construction whichwill now be described in detail.

The frame proper consists of upper and lower bars or boards, a and b,connected by upright bars 0, inserted thcrethrough and secured firmlytherein in any suitable manner. The uprights c are projected above thebar a in the form of tenons c, which enter and serve to hold in positionthe boardf, which overlies the frame and the upper edge of the apron, tokeep the latteriu place. The top board,f, is preferably fastened down inplace on the frame and the tenons c by a vertical bolt, X, passingthrough the board into the frame, as shown in Fig. 2, the same boltserving also to hold the top bar, y, in place. The framebar a is made ofsuch size that after the removal of the board f and the upper end of thebracket E the apron may be slipped upward endwise This removal of theapron without the necessity of disconnecting the frame or removing therolls is a very advantageous feature of theconstruction.

The upper roll 0 has its journals inserted through the bars a and b inan ordinary man ner. The lower roll, B, has its ends recessed to receiveinwardly-extending journals on a bracket, H, which slides at its upperand lower ends in grooves formed in the frame-bars, as shown. Thisbracket H is preferably made, as shown, of two angular parts, t and j,united by a bolt, k, this construction permitting their journals to bereadily inserted into the ends of the roller. the lower uprightframe-bar, 0, and provided on opposite sides thereof with twoadjustingnuts, Z and m, by means of which the bolt may be caused toslide the bracket H and roller B The bolt is extended through eudwise ofthe frame, so as to give the apron the required tension.

It will be perceived that the bolt K serves the double purpose ofuniting the two parts of the bracket Hi aud of adjusting the bracket asa whole within the frame to regulate the tension of the apron. In orderto permit con venient access to these adjusting-nuts without removingthe apron, I provide the latter, as shown in Fig. 1, with an opening,0,which, being brought opposite the ends, will permit the insertion of awrench. A flap,p,secured to the face of the apron and arranged to closebackward over this opening, prevents the straw or other matters fromentering the same. This flap should of course be arranged so that itwill be held in a closed position by the pressure of the grain thereon.

In order to increase the durability of the parts, I prefer to providethe roller B with a central tubular shaft, 8, the ends of which areprojected into the journals of the bracket H, as shown. A pin, 00,inserted as shown in Figs. 3 and 4-, rigidly unites the roller andshaft.

An oil-opening, t, formed in the upper side of the frame, communicateswith a groove, a, formed in the top of the bracket, and this groove inturn communicates through a hole, 22, with the interior of theroller-bearing, thus permitting oil to be readily introduced to both theupper and lower bearings without removing the belt. lhe lower journalserves as a cap or socket to retain the oil, which is thus preventedfrom saturating the apron and causing the same to become loaded withdust, as in machines of the ordinary construction.

Having thus described my invention, what I claim is 1. In combinationwith theroller-frame, the adjustable roller, and internal roll-adjustingdevices, the endless apron provided with an opening through which accessmay be had at will to said devices, whereby the tension of the apron maybe readily controlled.

2. In combination with, the roller-frame, a belt-sustaining roll,andinternal rolladjusting devices, the endless apron provided with theopening and with the flap or cover to close said opening.

3. In a butt-adjusting mechanism for a binder, the roll-carrying frameD, having its bars 0 extended upward to form tenons, in combination withthe removable top board seated upon and held in place against horizontalmovement by said tenons, as described, and a bolt or fastening to holdthe board from rising.

4-. In a butt-adjusting mechanism, the combination of the main framehaving the longitudinal bars a I), the rollers B O, sustained bybearings in said bars, the endless apron applied to said rollers, and anindependentlyremovable top board, f, applied to the frame, substantiallyas described, whereby the removal of the apron is permitted without removing the rolls and without disturbing the bearings in which they aresupported in the frame.

5. In combination with a supporting-framc, D, the roll-supportingbracket H, constructed of two parts, and the bolt It, applied asdescribcd, to serve the double purpose of uniting the parts of thebracket and of adjusting the bracket in the frame.

(5. The bracket H, provided with the tubular inwardly-extendingjournals, in combination with the tubular shafts, seated atits endswithin said journals, and the roller B, surrounding said shaft andsecured thereto, the ends of said roller being recessed to receive thejournals of the bracket.

7. In combination with the roller B, provided with thetubular shaft, aslidingbracket, H, supporting the journals of said roll, and providedwith an oil-opening and an oil-conducting groove in the upperend, andthe main frame D, supporting saidbracket, and provided with anoil-inlet, t, whereby the oil delivered through the last-named openingisconducted to both ends of the roll.

In testimony whereof I hereunto set my hand,

this 26th day of July, 1886, in the presence of two attesting witnesses.
